To add guard Daryn Colledge, the Dolphins had to free up a roster spot to stay at the 90-player limit. That move came Tuesday, with the club waiving rookie linebacker Marcus Thompson, an undrafted free agent from Rutgers.

The 6-foot-1, 250-pound Thompson notched 51 tackles and 5.5 sacks in 2013 for the Scarlet Knights, for whom he started 26 career games. He signed with the Dolphins on May 13.

Thompson will be on waivers for one day. If he goes unclaimed, he will be a free agent. In a feature written by the Dolphins’ website this spring, Thompson indicated other clubs had shown interest in him as a post-draft signing.
