The Indianapolis Colts worked out tight end Mike Flacco on Tuesday, according to a source.
He wasn't immediately signed to a contract, though.
Flacco was recently released from the Jacksonville Jaguars' practice squad.
The brother of Ravens quarterback Joe Flacco, Mike Flacco went undrafted this year after being selected as a third-team Division II All-American in his first season playing football at New Haven. He had spent time earlier this year with the San Diego Chargers but was cut in late August.
Last year marked the first time Flacco played football since he was in high school. He finished the season at New Haven with 30 catches for 591 yards and nine touchdowns in 10 games.
Flacco, 6 feet 5 and 245 pounds, ended his baseball career last April and was placed on the voluntarily retired list by the Boston Red Sox. He had been traded to the Boston organization from the Orioles in March 2013. In 2009, he was a 31st-round draft selection by the Orioles, out of the Community College of Baltimore County-Catonsville.
Meanwhile, the Colts worked out former Ravens wide receiver Jace Davis.
The Miami Dolphins worked out former Ravens cornerbacks Dominique Franks and Marc Anthony.
The Washington Redskins worked out former Ravens cornerback Bryan McCann.
