Breathe a little easier, Eagles fans. Brandon Brooks' injury isn't serious. 

The Eagles' starting right guard left the team's 17-9 preseason win early in the first quarter after suffering a right biceps injury. After spending some time on the sideline, he eventually went into the locker room. 

After the game, Brooks said the trip to the locker room was just precautionary and expects to be back on the field on Saturday morning for practice. Brooks said he just over-extended his arm a little bit in pass protection.  

The Eagles gave Brooks a big free agent contract this offseason in an attempt to solidify their weakest offensive line spot from 2015. But in the last few weeks, Brooks has had two injuries. He entered training camp with a hamstring injury and now hurt his right biceps. 

Lucky for the Eagles, this one isn't serious. With Lane Johnson's reported suspension looming and with Jason Peters' injury concerns, the Eagles can't afford to lose their big right guard. 

Backup center Josh Andrews also left Thursday's game early. No word yet from the team about his condition.
