Aaron Wilson of the Baltimore Sun reports that the Ravens are working out a number of tight ends on Tuesday now that they have placed on Dennis Pitta on season-ending injured reserve with a hip injury.
Davis and Mulligan are the most notable of the group given that they have played for a number of NFL teams.
The Giants signed Davis to a one-year contract back in April to add some much needed depth at tight end, but he was ultimately released a few weeks ago as they trimmed their roster down to 53 players.
Davis, 28, was a fifth-round selection of the Chicago Bears back in 2008 NFL Draft. He wound up signing a one-year contract with the Seahawks last year after he spent most of the offseason with the Browns. In 2013, he appeared in 15 games and caught 3 receptions for 32 yards receiving and a touchdown.
Mulligan, 29, is primarily a blocking tight end. He too signed a one-year contract with Chicago back in April, but was released last week as they made room for defensive back and receiver help.
Last year, he appeared in 15 games for the Patriots and caught two passes for 16 yards and a touchdown.
