Britton will throw a simulated game Thursday in an attempt to draw interest from several teams, Ken Rosenthal of The Athletic reports.
Eight teams will reportedly be in attendance for Britton's showcase, though the identity of those clubs hasn't been revealed. The 35-year-old lefty battled frequent injuries during the past two seasons, logging just 19 innings and generating a bloated 6.16 ERA and 2.00 WHIP across 25 appearances over that span.
