Thad Lewis was sent for X-rays following Sunday's Week 6 overtime loss to the Bengals and his right foot is in a walking boot.
Lewis played the entire game but was noticeably limping a bit in the second half. The Bills can ill afford to lose Lewis, who was promoted from the practice squad to make the start against Cincinnati in the wake of E.J. Manuel's (knee) injury. Lewis accounted for three touchdowns Sunday, turning the ball over just one time on a lost fumble. The Bills travel to Miami in Week 7.

Thad Lewis completed 19-of-32 passes for 216 yards and two touchdowns in Buffalo's Week 6 overtime loss to the Bengals.
Lewis added 17 yards and another all-purpose touchdown on seven rushing attempts. On the opening drive, Lewis scored from three yards out on a quarterback draw. He and the Bills stalled for much of the game thereafter before turning it on in the fourth quarter as they rallied to score two unanswered touchdowns and force the game into overtime. Those two Lewis scores went to Marquise Goodwin and Scott Chandler. Lewis is clearly better than undrafted rookie Jeff Tuel, but Lewis was spotted getting X-rays after the game. The Bills can't afford to lose him with E.J. Manuel (knee) still sidelined. Buffalo travels to Miami next week.

The Bills are working out free agent QB Matt Flynn.

eff the bills, who cares.

It makes you appreciate how tough Tannehill is. He's taken probably the worst beating that any quarterback has taken this year.

Rumor has it Flynn has an arm injury that is further limiting his already lacking velocity.

Didn't sound like Lewis was doing too bad yesterday but then he got hurt.

I would hope if Flynn is signed that Philbin could help identify his tendencies and have the defense react accordingly. His weak arm would let the defense focus on shutting down Spiller and Jackson.

I want Sunday to be a resounding win, not a close game where Miami plays down to the competition.

A source tells ProFootballTalk that Bills QB Thad Lewis has been diagnosed with a mild foot sprain.
Lewis' MRI revealed no ligament damage, leaving him day to day. There's a chance he can play through a mild sprain against the Dolphins in Week 7. If not, the Bills will need to add a quarterback as E.J. Manuel (knee) isn't close and Jeff Tuel is a developmental prospect they don't want to expose. Free agent Matt Flynn was in Buffalo for a workout Sunday.

Mario Williams has been beasting this year too... hopefully with our two weeks of preparation we've come up with a plan to contain him.
