The Cardinals fear that Maxx Williams is dealing with a major knee injury (Twitter link via NFL.com’s Ian Rapoport). The tight end will undergo additional testing today, but doctors say this will likely mark the end of his season. 
Williams was set to play a key role in the Cardinals’ offense this year, particularly after notching seven grabs for 94 yards against the Vikings in Week 2. Unfortunately, he’ll have to shift his focus to 2022 after five games, 16 catches, 193 yards, and one touchdown.
It’s particularly bad timing for Williams since he’s in his walk year. The 27-year-old (28 in April) is on course for free agency in the spring after his two-year, $7MM contract expires.
Williams was easily on pace for a career year. To date, his best showing came as a rookie when he recorded 32 catches for 268 yards and one TD. All in all, he’s got 102 career receptions for 994 yards and six scores between his time with the Ravens and Cardinals.
Without Williams, the Cardinals will move forward with Darrell Daniels, Demetrius Harris, and Travis Ross as their TEs. However, they’ll need to wait for clearance on Daniels before activating him from the COVID-19 list.
