Los Angeles Rams WR Van Jefferson, still not practicing after knee surgery, goes on IR play Can the Rams continue their dominance over the Cardinals? (1:07) Ryan Clark believes that the Cardinals do not have enough to beat the defending champs. (1:07) 2:04 PM ET Sarah BarshopESPN Staff Writer Close Covered the Packers for ESPN Milwaukee Marquette University graduate LOS ANGELES -- The Rams have placed wide receiver Van Jefferson on injured reserve, the team announced on Saturday. Jefferson has not practiced since having what was called minor knee surgery in August. Earlier in the week, Rams coach Sean McVay said Jefferson isn't dealing with a setback and is "on track, just kind of week-to-week right now." Jefferson will miss at least the next four games. In his absence, the Rams have turned to Ben Skowronek as their No. 3 receiver and have leaned more heavily on tight end Tyler Higbee . Last season for the Rams, Jefferson had 50 catches for 802 yards and six touchdowns.
