The Jacksonville Jaguars have signed tight end Mike Flacco, brother of Ravens quarterback Joe Flacco, according to a source. Mike Flacco went undrafted this year after being selected as a Division II third-team All-American in his first season playing football at New Haven, where the 6-foot-5, 245-pound player finished the season with 30 catches for 591 yards and nine touchdowns in 10 games. Flacco, 27, had spent time this year with the San Diego Chargers but was cut in late August. Last year marked the first time he played football since high school. Flacco played minor league baseball but ended his career in April 2013 and was placed on the voluntarily retired list by the Boston Red Sox. He had been traded to Boston from the Orioles that March. In 2009, the Orioles drafted him in the 31st round out of CCBC-Catonsville.
