+## Problem
+`get_one_player` in `app/routers_v2/players.py` returned a CSV response containing only the header row — player data was never included.
+
+## Root Cause
+`return_val = DataFrame(data_list).to_csv(header=False, index=False)` was called on line 625 when `data_list` contained only the header list. The player data row was appended to `data_list` on line 626 — after the CSV was already computed.
+
+## Solution
+Moved the `to_csv()` call to after `data_list.append(player_row)`. Single-line swap, no logic changes.
+
+## Files Changed
+- `app/routers_v2/players.py` (~line 625-651)
