The Cleveland Browns have activated TE David Njoku from injured reserve and elevated DT Joey Ivie to the active roster from the practice squad*. In addition, the club signed DE Cameron Malveaux to the practice squad.

Njoku recorded three receptions for 50 yards and a touchdown during the season opener at Baltimore on Sept. 13. He left the game with a knee injury and was placed on injured reserve on Sept. 14 and was designated for return on Oct. 7. A first round pick in 2017, Njoku has recorded 96 receptions for 1,116 yards with 10 touchdowns in 37 career games. Njoku is No. 85.

The Browns are 3-1 on the season after defeating the Dallas Cowboys in Week 4. Cleveland will look to improve to 4-1 when it takes on the Indianapolis Colts at home in Week 5.

However, the Colts game won't be an easy one for the Browns, as Indianapolis has arguably the best defense in the NFL at the moment. Cleveland quarterback Baker Mayfield will have to be on his A-game for the Browns to upset the Colts at home.

The former No. 1 overall pick will certainly need big games from Odell Beckham Jr., Kareem Hunt and Jarvis Landry as well.

Moreover, the Browns' defense—led by Myles Garrett—will have to get constant pressure on Colts quarterback Philip Rivers, otherwise it could be a long day for Cleveland.
