ORCHARD PARK, N.Y., Oct. 2 (UPI) -- Buffalo Bills defensive tackle Tyrone Robertson, inactive for the first four games of the season, is expected to be suspended an additional four games by the NFL for a repeat violation of the league's substance abuse policy.
The Bills placed Robertson on the reserve-suspended list Wednesday. According to ESPN, the league is expected to officially announce the suspension later this week.
A seventh-round pick by the Bills in 2001, Robertson will not be paid during the suspension, which will cost him $70,588. He will be eligible to return to the active roster on Oct. 27.
Robertson, 23, appeared in 12 games as a rookie, recording 27 tackles, including two sacks. However, he was frequently fined for being late to meetings.
To replace Robertson, the Bills activated linebacker Dominique Stevenson from their practice squad. Stevenson was the fourth of Buffalo's four seventh-round picks in this year's draft.
