Aviles, 34, was away from the team for 10 days from May 8-17 when his family learned of the diagnosis. The club has been supportive of Aviles and his family during their trying times, with players, coaches and team owner Paul Dolan shaving their heads in solidarity with Adriana.
A player can remain on the Family Medical Emergency List for three to seven days. Aviles will spend time with his family for the remainder of the first half and the All-Star Break, which runs through July 16.
