PATS NEWS -- Wide receiver Terry Glenn has reportedly filed a lawsuit against the NFL claiming that he has a disability that makes it difficult for him to adhere to certain rules in the league's substance abuse policy.

Glenn reportedly filed the complaint under the 'Americans with Disabilities Act', but the complaint did not specify what exactly the disability is that he suffers from.

He reportedly is claiming that he shouldn't have been suspended for the first four games of the season by the league for violating their substance abuse policy.  While he didn't test positive for using an illegal substance, he did miss the required drug test which is considered a violation.

After learning of the suspension Glenn left training camp without permission and was later placed on the "Left Camp" list by Patriots head coach Bill Belichick which would have caused him to miss the entire season.  That suspension was later overturned by an arbitrator.

Glenn served the suspension and returned for New England's week five game against the San Diego Chargers where he caught seven passes for 110 yards and a touchdown, but he injured his hamstring the following Wednesday and hasn't played or practiced much since.

He was inactive for the third straight week during Sunday's game against the Atlanta Falcons.
