The Cleveland Browns are exploring ways to acquire more offensive weapons before Tuesday's trade deadline, a league source told ESPN's Adam Schefter.

The Browns are looking for a deep-ball threat who can spread the field for the offense, as well as help for the running game, which has struggled all season.

Hue Jackson's Cleveland team is 0-7 entering Sunday's game against the Minnesota Vikings in London. Its offense ranks second worst in the league in points per game (14.7).

The Browns' receiving unit lost second-year player Corey Coleman to a broken right hand in Week 2, and Kenny Britt has been a free agent bust. Duke Johnson Jr., who is listed as a running back, leads the Browns in receptions (32) and receiving yards (314). In the backfield, Isaiah Crowell has failed to duplicate a strong 2016, amassing only 287 yards on 91 carries (3.2-yard average) on the year.
