The Arizona Cardinals have activated J.J. Watt from injured reserve in time for him to make an unexpected return for their Wild Card round clash with the Los Angeles Rams.

Watt was placed on injured reserve in November having undergone what was thought to be season-ending shoulder surgery in October.

However, the three-time Defensive Player of the Year has expedited his recovery and will line up for the Cardinals on Monday as they look to upset their NFC West rivals at SoFi Stadium.

Despite playing only seven games, Watt ended the regular season with the third-most quarterback pressures among Cardinals defenders with 32.

The Cardinals are looking to claim their first playoff win since the 2015 campaign when they lost the NFC Championship Game to the Carolina Panthers.
