Paul Perillo of Patriots Football Weekly helped break the story on Twitter:
Brandon Bolden suspended 4 games for violating the NFL's policy on performance enhancing substances. #Patriots— Paul Perillo (@pfwpaul) November 9, 2012
The substance that put him on the league's radar has not been released as part of the report. He hasn't played since injuring his knee against the Seattle Seahawks in the team's 24-23 loss on Oct.14.
Bolden asserted himself in the running-back rotation with starter Stevan Ridley and change-of-pace back Danny Woodhead after a strong preseason performance. The rookie out of Ole Miss went undrafted in 2012, but made the roster after being aided by a Shane Vereen injury.
He then had a coming-out party against the Buffalo Bills, rushing for 137 yards and a touchdown. He solidified himself as the No. 2 option behind Ridley and had then worked his way into a virtual time-share based on whoever has the hot hand in the Pats' offense on a series-by-series basis.
This isn't the first issue with PED use this season in the NFL. Cleveland Browns CB Joe Haden was suspended for the team's Week 2-5 games for the same offense.
The Patriots are eligible to bring back Bolden against the Houston Texans on Dec. 10. Make sure to get him out of your fantasy-football lineup right away.
