Clark Haggans' three-game suspension has been served, and the outside linebacker can re-join the 53-man roster this week. Haggans, signed to replace injured Parys Haralson (triceps), had to sit out the last three games as a result of a 2011 DUI when he was a member of the Cardinals. Haggans also had been arrested for DUI in 2004.
According to CSN Bay Area, the 49ers already have released Eric Bakhtiari, who had been signed when Haggans' suspension began. Bakhtiari mostly played special teams for the last three games, substituting in on defense only at the end of games and when Ahmad Brooks briefly left the Week 3 game against Minnesota.
Haggans, 35, suited up for the 49ers' first two contests but did not play. He had been granted a roster exemption -- meaning, he could stick around the 49ers practice facility -- while he served the suspension. The 49ers are likely to add him to the 53-man squad by 1 p.m. Tuesday.
