New Los Angeles Rams quarterback Matthew Stafford underwent a minor procedure on his right thumb in March, a source told Jourdan Rodrigue of The Athletic.

The procedure, which stemmed from an injury Stafford suffered in December, was elective and a "simple cleanup," a source told Rodrigue.

Stafford reportedly isn't expected to miss any portion of the Rams' spring workouts scheduled to begin later in April. Teams can begin gathering small groups as of April 19.
