Shortly after posting a game-high seven receptions for 86 yards in Buffalo, Cleveland Browns wide receiver Miles Austin notified team officials he was feeling discomfort in his abdomen. After further evaluation, it was determined Austin had sustained an injury to his kidney.

"Miles is a concern," Pettine said during his press conference on Monday.

Austin spent the night at Erie County Medical Center in Buffalo and will remain there Monday evening for precautionary reasons. Coach Mike Pettine said it wasn't clear which play Austin was injured on.

In 12 games this season, the 30-year-old veteran has 47 catches, 568 yards and two touchdowns.

"It was a frustrating loss," Austin said briefly after the game on Sunday.

News and Notes

• Tight end Gary Barnidge (ribs) was the other notable injury from the Bills game. There is no update on his status. Center Nick McDonald (ankle) was cleared by trainers before the game ended, but the team will monitor his status this week.
• Ryan Seymour filled in for McDonald at center, playing 51 of the 69 snaps on offense. Seymour, now officially in his second season from Vanderbilt, spent last season on the practice squad with both the 49ers and Seahawks. Sunday against the Bills marked his first-ever extensive NFL action.
• "You have to be prepared and ready," said Seymour. "I'm not getting as many reps in practice every week. Nick has been rolling with the ones. I have to put in extra effort and be ready to go when my number is called."  
• The Browns have not yet decided whether or not to place Tashaun Gipson (MCL) on the injured reserve list. The safety hurt his knee in the fourth quarter against the Falcons. Pettine said Cleveland may make a decision this week.
• Pettine didn't want to get into the specifics of rookie cornerback Justin Gilbert' illness that forced him to miss the game on Sunday, but the team expects him to be a full-go at practice on Wednesday.
• Pettine was very pleased with how Josh Gordon played against Buffalo. It wasn't the seven catches and 75 yards that stood out the most to Cleveland's head coach, either.
• "I thought he played hard. I thought he blocked," Pettine said. "There were a couple times where he…Just kind of comparing his blocking from his past to last week and even more so, I thought he was very aggressive. I thought he finished some runs well, his physicality and his intensity. I was upset with the penalty. I don't think there's a place for that. From a sense of urgency and how physical he was, overall we were pleased."
