James Carpenter cleared to practice, Charly Martin added to active roster

Seattle Seahawks offensive guard James Carpenter was medically cleared on Wednesday from a concussion and will practice with the team, head coach Pete Carroll told the team's website. Carroll was hesitant to say whether the second-year pro would regain his starting spot, adding that he'll take a "wait and see" approach to decide between Carpenter and John Moffitt at that guard slot.

The Seahawks were off on Tuesday and last practiced on Monday for a bonus session following a bye week. Carpenter's status then was still unclear.

Meanwhile, the team activated receiver Charly Martin, according to reporter Curtis Crabtree, while signing receiver Corbin Louks to the practice squad. Seattle had an opening on the 53-man active list following the suspension of safety Winston Guy.

Guy will miss four games due to a violation of the NFL's performance-enhancing substance policy. The suspension began on Tuesday and Guy can return to the active roster on Dec. 17. His agent said Guy was flagged because of taking an over-the-counter supplement that contained a banned substance.
