Arizona Cardinals tight end Ben Patrick has been suspended for four games for violating the NFL's substance abuse policy.
Patrick tested positive for the drug Adderall, an amphetamine, his agent Kevin Omell said on Monday.
The agent says Omell took the drug to stay awake while driving from Flagstaff to Phoenix during the team's bye week in mid-October.
According to Omell, Patrick got the pill from a friend who had used the drug to stay up late studying.
