Dolphins hosting Tarvaris Jackson, J.D. Walton along with Crabtree

The Miami Dolphins will be busy on Thursday, welcoming several free agents into their team facilities on visits. News yesterday indicated wide receiver Michael Crabtree would be in Davie today, with reports now adding quarterback Tarvaris Jackson and center J.D. Walton to the group.

The Dolphins, who will not match the offer extended by the Buffalo Bills to tight end Charles Clay, have about $17 million in salary cap space.

Adding Crabtree would give Miami a veteran wide receiver in a group of young wide outs, headlined by Jarvis Landry, Kenny Stills, and Rishard Matthews. The first round draft choice of the San Francisco 49ers in 2010, Crabtree started all 16 games last year for San Francisco, catching 68 passes for 698 yards, with four touchdowns. His best year was 2012, when he tallied 85 receptions for 1,105 yards with nine touchdowns.

Jackson joined the league in 2006 as a second-round selection of the Minnesota Vikings. he spent the last two seasons with the Seattle Seahawks, playing as the backup for Russell Wilson, after the 2012 season with the Buffalo Bills. He last started in 2011, during his first stint with the Seahawks, when he went 7-7 in 14 starts, completing 271 passes for 3,091 yards and 14 touchdowns with 13 interceptions.

Walton, a third-round draft choice of the Denver Broncos in 2010, spent last season with the New York Giants, starting all 16 games at center.  He has 52 appearances, all starts, in his 5 years in the league.

The Dolphins seem to have made a habit of signing all free agents who visit, so it is possible all three players could land contracts by the end of the day.
