FREMONT, Calif. (AP) -- Jacksonville running back Maurice Jones-Drew has a tendon strain in his left foot, and the Jaguars hope he won't miss any games.
Coach Gus Bradley said Monday that Jones-Drew will undergo an MRI and may sit out practice this week as a precaution. But he's encouraged that Jones-Drew could be ready to play Sunday in Seattle.
''We'll know more on Wednesday but by all accounts it looks pretty good,'' Bradley said. ''I know he felt good this morning so that's a positive sign. Good news for us.''
Jones-Drew was injured in the second quarter of the Jaguars' 19-9 loss to the Oakland Raiders. He had run for 2 yards on a second-and-goal play when Raiders safety Charles Woodson made a flying tackle after leaping over two other players. Jones-Drew limped off the field after being hit and did not return.
The 28-year-old running back, who missed 10 games with a foot injury last season, had just 27 yards on 10 carries before getting hurt. The 27 yards are the third-fewest of Jones-Drew's career when he has 10 carries or more.
Jones-Drew left the Jaguars locker room without talking to reporters following the loss to the Raiders.
After speaking with the running back and team trainers on Monday, Bradley was upbeat but added that even if Jones-Drew is cleared the Jaguars may hold him out of practice.
''He could, depending on what we find out,'' Bradley said. ''But we feel like he's got a chance to be back on Sunday.''
The news isn't as promising for quarterback Blaine Gabbert, who cut open the back of his throwing hand on a defender's helmet during the season opener against Kansas City on Sept. 8. Gabbert had some of the stitches removed, but is likely to miss a second straight game.
''He'll do some running and things like that, but as of right now we don't anticipate we'll have him on Sunday.''
Chad Henne passed for 241 yards and one touchdown in his first start since Gabbert went out, but the Jaguars continued to struggle to score.
One week after the offense was shut out in a 28-2 loss to the Chiefs, Jacksonville was held to a field goal through the first three quarters against Oakland until Henne's 13-yard pass to Clay Harbor with 2:53 remaining.
Part of the Jaguars struggles were self-inflicted. Henne was sacked five times, and Jacksonville had 10 penalties for 70 yards compared to just five penalties for Oakland.
''The penalties were the big issue for us,'' Bradley said. ''We had two that occurred on fourth down that extended drives. The penalties that we had contributed to 13 points. We need to clean those things up.''
The Jaguars are staying in Northern California and practicing at San Jose State with two straight games on the West Coast.
Notes: TE Marcedes Lewis, who has not played this season because of a calf injury, will attempt to run sprints on Tuesday. If all goes well, he could be activated for Sunday's game in Seattle. ... The Jaguars claimed cornerback Jamell Fleming, a third-round pick in 2012, off waivers from the Arizona Cardinals and signed defensive end Jacques McClendon. To make room, Jacksonville waived defensive back Marcus Burley and wide receiver Jeremy Ebert. The team also signed Chris McCoy to the practice squad.
