A source told ESPN that Porzingis is experiencing irritation in the knee but hopes to play in Game 2.
Meanwhile, Clippers guard Patrick Beverley was added to the afternoon injury report, listed as questionable due to a left calf strain. Beverley missed the last five games of the seeding schedule due to a left calf strain but started Game 1, scoring eight points in 20 minutes.
The 7-foot-3 Porzingis missed 10 games in late December and January because of soreness in his right knee. He tore the ACL in his left knee in February 2018 in what ended up being his final game with the New York Knicks and sat out the entire 2018-19 season, when he was traded to Dallas.
Porzingis had 14 points and six rebounds in the Mavs’ Game 1 loss Monday before being ejected early in the third quarter, when he was whistled for his second technical foul stemming from a confrontation with Clippers forward Marcus Morris Sr.
Porzingis, who is participating in his first playoff series, averaged 20.4 points, 9.5 rebounds and 2.0 blocks per game during the regular season. He earned second-team All-Bubble recognition after averaging 30.5 points, 9.5 rebounds and 1.5 blocks during the seeding schedule at the NBA’s Walt Disney World campus.
