Browns LG Jason Pinkston (blood clot in lung, injured reserve) has been cleared to begin weightlifting and conditioning.
Pinkston was enjoying a fine season before going down in Week 6, but his career is still in the balance. Head coach Pat Shurmur was uncertain of Pinkston's long-term outlook, "It's hard for me to tell what the long range is for him." John Greco has filled in admirably at left guard for Cleveland. Pinkston will enter the third year of his four-year rookie deal in 2013.
