Cleveland Browns wide receiver Mohamed Massaquoi saw parts of his previous two seasons wiped out by concussion-related symptoms.
This season has picked up where those campaigns left off.
Massaquoi exited Friday night's preseason-opening 19-17 victory over the Detroit Lions with a head injury after he caught Brandon's Weeden's first NFL pass in the first quarter, Mary Kay Cabot of The Plain Dealer reported.
It's a disappointing start for Massaquoi, whom the Browns touted as an offseason standout primed for a breakout season.
This year is much closer to Massaquoi's final chance in Cleveland. The 2009 second-round draft pick has failed to develop into a No. 1 wideout, and he pulled in a career-low 31 passes for 384 yards in 13 starts in 2011. He suffered a string of concussion-related symptoms last season and was the subject of a brutal 2010 hit from Pittsburgh Steelers linebacker James Harrison.
Friday's game wasn't a promising opening act for Massaquoi, but it was one that should concern the Browns.
UPDATE:Browns coach Pat Shurmur said after the game that Massaquoi suffered a concussion, according to Cabot.
