The Boston Celtics beat Philadelphia 123-101 to replace the 76ers at the top of the NBA Eastern Conference as Jayson Tatum outshone his former teammate Jaylen Brown in a much-hyped showdown Tuesday.

Brown’s first regular-season clash against the Celtics team he called home for a decade played out against reports of a beef with his 2024 NBA title-winning partner Tatum.

The two men have exchanged cryptic public barbs, apparently disagreeing over Tatum’s knowledge of — or role in — Brown’s shock trade this summer to the Sixers.
