Daniel Helm

Helm was on the Bucs' practice squad, but with Jordan Reed (knee) sidelined for the next two months, they need bodies. Helm is familiar with coach Kyle Shanahan after spending time with the Niners in recent seasons. George Kittle and Ross Dwelley are the top two options still.

Helm was signed from the practice squad in December following Garrett Celek's placement on IR. The latter has decided to retire, so there is a chance the undrafted rookie sticks with San Francisco if the team liked what they saw in practice during his rookie campaign. Helm wasn't much of a receiving threat at Duke, so his fantasy upside is limited, especially if he remains on the back end of a roster.

Helm's chance on the 53-man roster comes following the placement of Garrett Celek (back) on injured reserve. The undrafted rookie out of Duke will slot in as the No. 4 tight end on San Francisco's roster.

Helm will have his work cut out for him in order to earn a spot on the 49ers' final roster. He will be competing against Levine Toilolo, Kaden Smith, Ross Dwelley and Tyree Mayfield for the depth chart's No. 3 spot.
