Dwelley caught his lone target for 56 yards in Sunday's 31-14 win over the Rams.
Dwelley -- normally a backup tight end -- played most of his 19 offensive snaps at fullback in place of Kyle Juszczyk (thumb). The 27-year-old saw only one target, but he made it count by running a crisp wheel route out of the backfield for a huge gain. With the 49ers entering a bye week, there's a good chance Juszczyk returns before the team's next game against the Chargers on Sunday, Nov. 13. Dwelley currently isn't a roster-worthy fantasy option.
