Eagles starting quarterback Nick Foles left Sunday's Week 9 game at Houston on the final play of the first quarter with a shoulder injury.

Foles took a sack from Whitney Mercilus, getting slammed to the turf. He appeared to land directly on the non-throwing shoulder that has been bothering him for a while now and walked to the locker room for X-rays.

After the game sources confirmed that Foles suffered a broken collarbone when he was sacked by Mercilus.  A Monday MRI will determine exactly how long he'll be out, but best-case scenario would be a 4-6 week timetable.  Keep in mind, Packers quarterback Aaron Rodgers suffered the same injury last season and missed eight weeks.

Foles was 10-of-13 for 124 yards with one touchdown and one interception before giving way to Mark Sanchez.

Sanchez threw for 202 yards and two touchdowns in three quarters Sunday to help the Eagles improve to 6-2 on the season.
