NBA
Felton drove past Randy Foye and banked in a shot high off the glass. He then got a piece of Kenneth Faried's jumper at the buzzer, causing the ball to wind up short.
Danilo Gallinari scored a career-high 47 points, including eight in the first overtime and nine in the second.
Denver had a chance to win in regulation, but Faried's jumper rolled off the rim. Dallas had a shot to claim victory at the end of the first overtime, only to have Monta Ellis' long shot clang off the iron.
Dirk Nowitzki had 25 points and Richard Jefferson added a season-high 24 (see full recap).
Bucks win, trim magic number to one
NEW YORK -- Giannis Antetokounmpo returned to the lineup with 23 points and moved the Milwaukee Bucks to the verge of a playoff spot with a 99-91 victory over the New York Knicks on Friday night.
The Bucks lowered their magic number to one for clinching a playoff berth, which would complete a remarkable turnaround from an NBA-worst 15-67 record last season. They would have secured a place in the postseason with losses by either Boston, Brooklyn or Indiana, but all three won Friday.
The Bucks can wrap up their spot Sunday at home against the Nets, the team Jason Kidd led to the playoffs last season before taking over the young Bucks.
Langston Galloway scored 20 points and Lance Thomas added 16 for the Knicks, who are closing in on following the Bucks as the NBA's worst team (see full recap).
