Cleveland Browns defensive end Desmond Bryant has been placed on reserve/non-football injury with an irregular heartbeat and will miss the rest of the season.
According to the Akron Beacon Journal, Bryant has been dealing with the issue over the last two seasons.
Bryant started all 12 games for the Browns this season and registered 45 tackles and 3 1/2 sacks after signing a five-year, $34 million contract with the team in March.
According to a Browns team spokesman, Bryant is having "a minor heart procedure" this week.
The 6-foot-6, 310-pound Bryant reported the symptoms Monday, a day after he played 47 of 74 snaps and finished a 32-28 loss to the Jacksonville Jaguars.
The Browns announced Wednesday that receiver Brian Tyms was signed off the practice squad to take Bryant's place on the roster.
In another development, doctors cleared quarterback Jason Campbell to return to practice Thursday, according to ESPN.com.
Doctors will still need to clear Campbell to play in a game from the concussion he suffered against the Pittsburgh Steelers on Nov. 24. The Browns visit the New England Patriots this week.
Campbell will get some reps at practice Thursday, along with the other quarterbacks. If he is cleared in time, he would start Sunday, according to ESPN.com.
Quarterback Brandon Weeden still hasn't been cleared to practice from the concussion he suffered last Sunday against the Jacksonville Jaguars.
Veteran quarterback Caleb Hanie, who signed with the Browns earlier this week, and Alex Tanney, who was signed last week off the Dallas Cowboys' practice squad, split first-team reps in practice Wednesday.
