We don't know how long the Lynx season will last with the playoffs set to begin next week. We do know that Sunday is the final regular-season game — and the last time fans are guaranteed to see Lindsay Whalen playing in a Lynx uniform.

The Lynx host the Washington Mystics at Target Center at 6 p.m. Sunday. Whalen, who on Monday announced her decision to retire at season's end after 15 seasons in the WNBA, will be honored during an on-court, postgame celebration.

In anticipation of a large crowd to see the Hutchinson native and former Gophers standout, the Lynx have made additional upper-level seats available.

Sunday is also Fan Appreciation Night presented by the Star Tribune. The first 2,500 ticket holders to enter the doors will receive a team poster. All fans will receive a commemorative Lindsay Whalen card.
