(SPORTS ILLUSTRATED) — Quarterback Tom Brady exited practice early Wednesday with a left knee injury, a development that had the Patriots feeling a little jittery if nothing else.

But the Patriots apparently can rest easy.

Multiple outlets, including ESPN, NFL.com and CBS Boston, have reported that Brady’s MRI came back clean, and that the Patriots’ QB is day-to-day with a knee sprain. He is expected to undergo more tests tonight.

Brady is five years removed from the infamous ACL tear he suffered at the onset of the 2008 season, when the Chiefs’ Bernard Pollard lunged at him on a tackle attempt. That injury occurred in Week 1 of the season, and Brady sat out the remainder of the year.
