I was Pilot Flying on flight to ZZZ. The flight went normally. After I called landing gear down; a few moments later we got anti-skid inop on final approach. We elected to continue the approach to landing on Runway XX in ZZZ which was 10;000 feet long and dry. We had a normal landing and didn't use the brakes until between 80 and 90 knots. Then we got a PSEU [Proximity Electronics Unit] light as we cleared the runway. We taxied to the gate normally and shut the engines down; then the PSEU light extinguished.Next; the First Officer notified us of damage to the left main landing gear door assembly as well as a landing gear door panel was missing from the aircraft. During our flight; there was never any indication at all. During takeoff; cruise; descent; or approach and landing; there was [not] any issue or concern with the left main landing gear.
B737-700 First Officer reported finding the left main gear door and door assembly missing while conducting the post flight check.
