The Boston Red Sox placed left-hander Chris Sale on the 10-day injured list with left elbow inflammation on Saturday, and he could be finished for the season.
Among the doctors who will examine Sale's medical tests is noted orthopedic surgeon Dr. James Andrews.
Sale threw 6 2/3 innings and struck out 12 on Tuesday in a win against the Indians in Cleveland. Dombrowski told reporters that Sale reported being stiff in the following days and informed team doctors on Friday. He had medical tests on Saturday that will be evaluated on Monday, Dombrowski said.
On the season, he is 6-11 with a 4.40 ERA. He got off to an 0-5 start and there were worries early in the year about his velocity, when his fastball averaged 89.1 mph during an April game against Oakland, which was the lowest in a single game in his career.
--Toronto Blue Jays rookie standout Vladimir Guerrero Jr. was scheduled to undergo an MRI exam after leaving Saturday's game against the Seattle Mariners with a left knee injury.
Guerrero, a third baseman, was injured in the second inning when he cut in front of shortstop Bo Bichette to glove a grounder and made an awkward throw to first. Seattle's Aaron Nola beat the throw.
"He felt a little tweak in his knee so we took him out just in case," Toronto manager Charlie Montoyo told reporters after the 4-3 loss to the Mariners. "So he's going to get an MRI to make sure he's fine. I'll know more about it tomorrow."

Arrieta is 8-8 with a 4.64 ERA in 24 starts this season, his second with the Phillies. He has a 5.76 ERA over his past 13 starts, allowing 84 hits and 25 walks in 65 2/3 innings.
--Los Angeles Dodgers left-hander Julio Urias accepted a 20-game suspension without pay related to his violation of Major League Baseball's domestic violence policy in May, commissioner Rob Manfred announced.
Urias must serve 15 games. MLB said the five games he missed while on administrative leave from May 14 to May 21 will count as part of the 20-game suspension. Urias agreed not to appeal the penalty, according to MLB.
Urias was arrested on suspicion of domestic battery on May 13 after an incident at a Los Angeles shopping mall. A witness told police that Urias shoved his companion, but her statement to police was that she fell as they argued. The Los Angeles City Attorney's office announced in early June that no charges would be filed.

The 34-year-old pitched just 6 2/3 innings over seven games this season, going 0-1 with a 5.40 ERA. He was signed to a two-year, $23 million deal in the offseason. Overall, Robertson has a career 53-33 record and 137 saves in 661 games, all relief appearances, with a 2.90 ERA in 12 seasons.
