Hamilton spent the weekend getting treatment to address an ankle sprain he sustained in Thursday's 35-34 win over the Bengals, Brian Wacker of The Baltimore Sun reports.
Per Adam Schefter of ESPN, head coach John Harbaugh said after the Week 10 win that Hamilton's injury wasn't considered serious, but Monday's update casts a shadow of doubt on his status heading into Sunday's game against the Steelers. The Ravens' first official practice report of Week 11 will be released Wednesday and should shed more light on his potential availability for this weekend.
