Washington Redskins quarterback Robert Griffin III will have more tests done on his injured right knee because an MRI taken showed inconclusive results.
Redskins coach Mike Shanahan said Monday that a previous anterior cruciate ligament tear clouded results of the test and that Griffin would visit Dr. James Andrews in Pensacola, Fla., on Tuesday.
"There is a concern," Shanahan said of Griffin's condition. "That's why he's going to go see him. Anytime you get an MRI and you have old injuries (to) the LCL, ACL, (Andrews) wants to give him a physical exam himself and give him a number of tests and evaluate him in person."
Griffin tore his ACL at Baylor in 2009. He sprained the knee during a game on Dec. 9 and missed one game. He reinjured the knee twice during Sunday's NFC wild-card playoff loss to the Seattle Seahawks. Griffin was reinjured in the first quarter but remained in the game until he was hurt again with 6:19 remaining in the game.
Griffin's exit came in the wake of a USA Today report that Andrews, who is on retainer with the Redskins, had not cleared Griffin to re-enter the Dec. 9 game when he was initially injured.
"There was no miscommunication with Dr. Andrews," Shanahan said. "It doesn't matter. I asked Dr. Andrews if Robert is OK to be in the game and he said yes. ... I don't sit down with him and say, 'Hey, did you give him a proper evaluation?' I asked him, 'Is it OK if he goes back in the game?' He says yes or no. He said yes."
--And then there were five openings left.
Two of the seven head coaching vacancies in the NFL were filled Monday. Andy Reid was introduced as the new head coach of the Kansas City Chiefs, while Doug Marrone took over as head coach of the Buffalo Bills.
Reid, who was fired at the end of the 2012 regular season after 14 years as head coach of the Philadelphia Eagles, replaces Romeo Crennel, who was also fired at season's end. Marrone replaces the fired Chan Gailey.
"The Chiefs have always had a passionate fan base, and I'm looking forward to Sundays at Arrowhead Stadium," Reid said. "We've got a lot of work to do to get ready for next season, and we are going to get started immediately."
Reid was fired by the Eagles following a 4-12 season. He was reportedly close to being named the Arizona Cardinals coach a day after being let go by Philadelphia, but he opted for Kansas City instead.
In Buffalo, Marrone said he would incorporate a "Moneyball" type of concept in evaluating talent. The team announced last week that it would start an analytics department.
While many inside the sport insist that statistical analysis does not work in football as it does in baseball, Marrone said it would be an important part of the team.
"We want to use that to be in the cutting edge and push us forward," said Marrone, 48, who was 25-25 in four seasons at Syracuse University before taking the Buffalo job. "It's part of what we do. It's part of our planning; it's part of our process."
Buffalo's 13-year playoff drought is the NFL's longest active streak. The team has not had a winning record since 2004, when it finished 9-7.
--Indianapolis Colts offensive coordinator Bruce Arians remained in a Baltimore hospital Monday for treatment of blood pressure issues and dizziness, according to ESPN.
Arians was hospitalized Sunday because of an undisclosed illness, and he missed the Colts' AFC wild-card loss to the Baltimore Ravens. A team spokesman said that tests came back negative but doctors want Arians to remain in the hospital until his blood pressure stabilizes.
Arians went to the hospital Sunday morning after reportedly feeling dizzy. He served as the Colts' interim coach when Chuck Pagano was diagnosed with leukemia in late September. The Colts went 9-3 under Arians.
Arians has drawn interest from the Chicago Bears and Philadelphia Eagles as a head coaching candidate.
--The Cleveland Browns reportedly interviewed Montreal Alouettes coach Marc Trestman for their head coaching job on Monday, according to multiple reports. The Browns were to meet with Trestman in Chicago, where Trestman was to interview for the Chicago Bears' head coaching job, according to ESPN.
Trestman is signed with the Canadian Football League team through 2016, but the team may let him out of the contract if he lands an NFL job. He has coached them to three Grey Cup games in five years, including winning the championship in 2009 and '10. He was the CFL's Coach of the Year in 2009.
Prior to his move to Canada, Trestman served as offensive coordinator of the Browns (1988-89), San Francisco 49ers (1995-96), Cardinals (1998-2000) and Oakland Raiders (2001-03).
--David Caldwell had a third interview for the Jacksonville Jaguars' general manager job on Monday, according to NFL.com. Caldwell is in his first season as the Atlanta Falcons' director of player personnel. He has been with the Falcons for five years. Previously, he was a scout during his 10 years with the Colts.
