49ers place RB Elijah Mitchell on IR, add RB Marlon Mack

Elijah MitchellThe series of injuries continued with an MCL sprain. This is considered a rather serious MCL problem, with Kyle Shanahan expects his starter to be out for about two months. As such, Mitchell landed on the 49ers’ IR roster on Tuesday.

The 49ers brought in several fullbacks for auditions on Tuesday. Old friend Tevin Coleman, Devonta Freemanex-Jet La’Mical Perine and ex-Lion Godwin Igwebuike came for practices,’s Field Yates tweet. Marlon Mac visited with the team, and that seems to be the direction it will go. 49ers sign Mack to practice squad,’s Adam Schefter tweet.

This will be Mack’s first move out of AFC South; the former fourth-round pick spent his career with the Colts and Texans. Houston, however, didn’t stop the former 1,000-yard rusher on its 53-man roster from skipping training camp. The Texans cut Mack, moving their roster to 53, then released him from their practice squad.

Mack, 26, saw an Achilles tear in September 2020 derail his career. The Colts are looking to the second round of 2020 Jonathan Taylor, and although they re-signed Mack in 2021, the latter didn’t see much action last season. The Colts discussed possible trades before last year’s deadline, and the 49ers were one of the teams to express interest. But Mack played his second contract with the Colts, residing behind Taylor and Nyheim Hines on the depth chart.

Mack signed his second consecutive one-year, $2 million contract this offseason, joining the Texans, but will come to San Francisco for P-squad money. Mack, who rushed for 55 yards against the 49ers in this year’s Texans preseason finale, rushed for 2,099 yards from 2018-19.

Freeman and Coleman, of course, teamed up as part of powerful Falcons backlines during the 2010s. They parted ways in 2019, with Coleman signing with the 49ers. Freeman also played for Shanahan in Atlanta, starting the team for Shanahan’s two OC seasons. Coleman signed a two-year contract with the 49ers in 2019 and played with a former 49ers assistant Mike LaFleur in New York last season. Perine’s Jets pass also overlapped with LaFleur’s.

For now, Mack is the pick of the 49ers. The sixth-year veteran joins a team Jeff Wilsonthird-round pick Tyrion Davis Price and rookie Jordan Mason at running back. Wilson is expected to start for the 49ers during Mitchell’s absence, and the 49ers played Mason — an UDFA from Georgia Tech — against Davis-Price in their opener.
