Losing Revis would be a major blow to a Bucs secondary tasked with reigning in Calvin Johnson. Revis had shadowed Johnson all over the field before his exit, limiting the game's best receiver to four receptions for 61 yards. Johnson has already made two more grabs with Revis off the field.
The Bucs are having to adjust by moving to more Cover 2 looks, which should open up some running lanes for the Lions up the middle.
The injury occurred just before the end of the half, with the defender limping off the field and heading back into the locker room. He is currently back on the sideline wearing his helmet.
Revis has 30 tackles, seven pass defenses and one interception so far in 2013. He had three tackles before exiting against the Lions.
