Free-agent offensive guard Justin Blalock visited the Detroit Lions on Thursday and has apparently left without a deal.

A source close to the situation said the Lions' visit with Blalock was good and that the 31-year-old could be a good fit for Detroit. The Lions are weighing moving on from 31-year-old left guard Rob Sims, who is also a free agent.

The source said Blalock has interest from the St. Louis Rams and Tennessee Titans. The St. Louis Post-Dispatch has reported Blalock also has plans to visit the Rams.

Blalock, who was a second-round pick by Atlanta out of Texas in 2007, has played in 125 career games with the Falcons. He graded out as the 25th-best guard by Pro Football Focus last season and allowed 20 quarterback hurries and three sacks, according to PFF.

The 6-foot-4, 326-pound Blalock was cut by Atlanta in February, meaning that the team signs him won't have him count against any 2016 compensatory selections.
