49ers meet with veteran running backs Duke Johnson, Lamar Miller

Johnson caught on with the Jaguars earlier this month but was released after just nine days on the taxi squad. Johnson, 27, did not see the field during his lone week in Jacksonville, residing as an insurance option behind the likes of James Robinson, Carlos Hyde and Dare Ogunbowale. A former third-round pick, Johnson began his career with five straight seasons of 400-plus receiving yards. He topped out at 693 for the 2017 Browns, despite having started just 12 games in that span.

Miller has been on the market ever since he was released by Washington in August. The 2018 Pro Bowler, who has two 1,000-yard rushing seasons on his resume, has not been the same since a torn ACL wiped out his 2019.

Yeldon, 26 in October, spent the offseason with the Bills. After a 182-carry rookie campaign, the former second-rounder ended his Jaguars stay as Jacksonville’s third-string running back behind Leonard Fournette and Carlos Hyde. Still, Yeldon managed a respectable 4.0 yards per carry last season and has hit the 5.0 ypc mark in the past.
